If you could trigger the IMRC motor by use of a RPM switch (this type of switch is commonly used in nitrous systems), then you could retain the EECIV PCM, though you would still have to buy the IMRC and cable ($150 or so new). Of course you are going to have to modify fuel lines and injector wiring harness, source a later model fuel rail, and buy a MAF calibrated for 19# injectors.
On a 95 there are only two good reasons I can think of for going with an SVT LIM ?? larger throttle bores and 19# injectors. However, IMHO, the stock 17# injectors in good condition flow enough to not be a problem for typical bolt-on mods. I have read posts from people making well in excess of 200HP on 2.5Ls with 17# injectors. I know that you know this but it is still worth saying ?? larger injectors are only needed (and only make power) if there is adequate, properly calibrated airflow.
So except for the most highly modified stock 95 2.5Ls (head work and SVT cams at minimum) that really leaves one reason to use an SVT LIM ?? larger throttle bores. The 95 LIM castings are ??simple? and a competent machinist should be able to bore them out from 31/32 mm to the ST200 (2000 SVT) 34/35 mm size without difficulty. The real trick is sourcing or fabricating larger butterfly valve plates for the secondaries. This whole operation should cost less than a new ST200 LIM. Whala! Bolt on SVT LIM performance for 95 2.5Ls!
Just don??t try this if you plan to later upgrade your block to 3.0L. In that case you might as well solve the 19# injector question now because you will surely need them later.
